Military prosecutors have raided a division at Air Force headquarters that oversaw the initial investigation into a sexual assault case brought forward by an Air Force noncommissioned officer(NCO) who later committed suicide.

The Defense Ministry said Wednesday that it was executing a search warrant at the Air Force legal affairs department to investigate the initial handling of the case that was reported back in March and the alleged leak of the victim's personal information by the public defender.

The public defender also belongs to this bureau and is accused of failing to properly defend the client and holding no face-to-face meetings with the NCO. 

The master sergeant who died in May was under the 20th Fighter Wing and later transferred to another unit after reporting the assault.
